The 21-year-old Dutchman has started all seven of United's games this season but was hooked at half-time following an erratic 45 minutes in the weekend win over Liverpool.

Luke Shaw's impressive display and Anthony Martial's goalscoring debut highlighted United's dependence on their younger players against Liverpool, and Memphis believes the expensive age group can help each other develop.

“It's a new experience for me playing in the Premier League, so I have to improve and I know that,” he admitted.

“Anthony and I are both young, so we can help each other, we can ask each other questions. It's the same with Luke Shaw, I talk a lot with him. He has played longer in the Premier League than me so I have a lot of questions for me and he helps me also, so we can all help each other.”

“I think about that and I will improve in training, that's what I do always, keep my head up and work on it. I think I can do better in games.”

Memphis dominated the Eredivisie on a weekly basis at the Philips Stadion, where his goals helped secure PSV's first title in seven years and propel them into pot 1 of the Champions League.

Although professional ahead of Tuesday night's game, he could not hide a soft spot for his former club.

Memphis was poor in United's win over Liverpool

“Of course, I was playing for 10 years for PSV before I came to Manchester United, so it's a special feeling for me seeing my old teammates again and I look forward to it,” he reminisced.

“I think when I came on the pitch here the first time I was very young when I made my debut.

“So I will think about that when I walk on the pitch and train tonight, but tomorrow is a different thing. It will be interesting to see what we can do and we can do a good job here.”

Memphis has shone in the Champions League

Memphis also confirmed he would not restrain himself if he scored for United in front of the supporters who once adored him.

“A lot of people ask that question to me,” he revealed.

“Still, for me it's a game and if I score I will celebrate. I play for Manchester United now, so I will celebrate and of course I have respect for PSV.”

Memphis struggled again in the Premier League

Van Gaal, sat beside his compatriot, defended Memphis' impact at the club and urged United supporters to be patient.

“As a manager, you are never satisfied but he is doing well,” Van Gaal explained.

“He has played every game, until now, as you know it's not so easy. It's a high rhythm in the Premier League but he has to adapt to that high rhythm and he shall improve, I think.

“The Eredivisie is younger and younger and that's why you have to be patient, and I have to be patient for Memphis and the fans also. But also for Jesse Lingard, Andreas Pereira, Adnan Januzaj or that kind of players.

“You cannot demand players from 19 or 20 to be consistent and you have to accept that, and the Eredivisie is very nice to watch and the tactical solutions are very nice to watch also.

“But, of course, they are young and I think the pressure on the ball is less and the PL is very difficult to play and now Memphis is seeing that.”
